I'd previously thought that cannabis would take away everything bad.
This may still be true, but in the ancient times, cannabis was indeed used as medicine, often for fatal causes.
I've been overusing it, and I will probably not use it until December or so, and even then, just once a week.
NAC really does help and I need 2000 mg per day.
What does nicotine do ? Being away from cannabis has made me addicted to nicotine, at least for now. I think it'll also pass.
